In conditions when the volume of government orders for defense products may significantly decline, enterprises of the radioelectronic industry are faced with the need to move to civilian product markets, which will stabilize the order portfolio and reduce macroeconomic and technological risks. The article presents the main approaches to the analysis of the trend potential of complex technical systems on the example of unmanned aerial vehicles. Methods for assessing the quality of complex technical systems at different stages of the development of the potential of complex technical systems in the structure of the life cycle are proposed. A hypothetical fragment of a chronological analysis of the potential state of complex technical systems with a planning horizon of five to ten years is presented. The proposed approaches and mathematical models make it possible to predict the potential and to optimize the consumer characteristics of complex technical systems, based on the requirements of customers, the development of their needs, as well as on the implementation of advanced standardization.

Planning Algorithm

In this article, an online path planning algorithm for multiple unmanned aerial vehicles (UAVs) has been proposed. The aim is to gather information from target areas (desired regions) while avoiding forbidden regions in a fixed time window starting from the present time. Vehicles should not violate forbidden zones during a mission. Additionally, the significance and reliability of the information collected about a target are assumed to decrease with time. The proposed solution finds each vehicle’s path by solving an optimization problem over a planning horizon while obeying specific rules. The basic structure in our solution is the centralized task assignment problem, and it produces near-optimal solutions. The solution can handle moving, pop-up targets, and UAV loss. It is a complicated optimization problem, and its solution is to be produced in a very short time. To simplify the optimization problem and obtain the solution in nearly real time, we have developed some rules. Among these rules, there is one that involves the kinematic constraints in the construction of paths. There is another which tackles the real-time decision-making problem using heuristics imitating human-like intelligence. Simulations are realized in MATLAB environment. The planning algorithm has been tested on various scenarios, and the results are presented.

An approach to assessing complex technical systems at an early stage of their development is considered. Complexes with multifunctional dual-use unmanned aerial vehicles are being investigated as complex technical systems. The nov-elty of the work lies in the integration of the assessment by structuring the methods and stochastic models of the analy-sis of complex technical systems in the technological computerized environment of the developer, choosing a decision-making strategy at the stages of preliminary design, including the method of expert assessments. Using the example of unmanned aerial vehicles (UAVs), the technology of choosing a rational version of complex technical systems from among the alternatives of the formed model range using an information and analytical system (IAS) is shown. The IAS implements a procedure for multi-criteria assessment of complex technical systems based on the methods of expert assessments. The primary results of a comprehensive assessment of reconnaissance-strike and strike complexes of multifunctional UAVs weighing 0.3-2 tons have been obtained.

The article presents a summary of the method for predicting the technical potential of a complex technical system. The method consists in considering the life cycle curve in the form of a group of indicators reflecting not only the technical side of the functional characteristics of the product produced or the volume sold in a short time interval, but also indicators of competitiveness and equipment of the enterprise implementing this type of products. A model for assessing industrial competitiveness, including the interpretation of interval characteristics, is presented, and a graphical representation of the life cycle curve in an enlarged composition is also presented.

Improved Performance

The advancement in technology has seen a rapid increase in the use of unmanned aerial vehicles for various applications. These unmanned aerial vehicles are often equipped with the imaging platform like a camera. During the unmanned aerial vehicle flight, the camera is subjected to vibrations which hamper the quality of the captured images/videos. The high-frequency vibrations from the unmanned aerial vehicle are transmitted to the camera. Conventionally, passive rubber mounts are used to isolate the camera from the drone vibrations. The passive mounts are able to provide reduction in response near the resonance. However, this comes at the cost of amplification of response at the higher frequency. This article proposes an active vibration isolation system which exhibits improved performance at the higher frequencies than the conventional system. The active isolation system consists of a contact-less voice coil actuator supported by four springs. Experiments are carried out to study the effect of vibrations on the quality of images captured. The characterization of drone vibrations is also carried out by recording the acceleration during different flight modes. The performance of the proposed isolation system is experimentally validated on a real drone camera subjected to the recorded drone acceleration spectrum. The isolation system is found to perform better than the conventional rubber mounts and is able to reduce the vibrations to a factor of one-fourth. It can be effectively used to improve the image acquisition quality of the unmanned aerial vehicles.
